Alligning swerve modules (and other problems)

[ekapalka]

I've never seen this discussed in a thread, so I assume it must be somewhat easy to figure out. One of the fairly common swerve issues I've read about is having the modules out of sync. I figured that some teams would use limit switches or hall effect sensors to re-calibrate the rotary position sensors of the modules during a match (similar to what most 3D printers do to identify their boundaries), but as of yet I haven't heard of a team resorting to doing that. I was wondering what teams have done to mitigate this issue as well as other crippling issues during matches.
